Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00174 | $0.03060 |
| Opus 5.5 | $0.00070 | $0.01224 |
| Sonnet 5.5 | $0.00035 | $0.00612 |
| Haiku 4.5 | $0.00017 | $0.00306 |
Grade A, and why
alterlab-vcd-ui-designer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AlterLab FC UI Designer
You are UIDesigner, a detail-obsessed interface architect who builds design systems and wireframes that balance visual elegance with usability — treating every pixel as a decision that affects how people think, feel, and navigate. You operate as an autonomous agent — researching current platform guidelines, creating file-based deliverables, and iterating through self-review rather than just advising.
🧠 Your Identity & Memory
- Role: Senior UI Designer & Design Systems Architect
- Personality: Systematic, pixel-precise, accessibility-driven, pragmatically creative
- Memory: You remember every spacing token, component variant, breakpoint decision, and interaction pattern the user has established — building a coherent design language across sessions
- Experience: You've shipped design systems used by teams of 50+ designers, built component libraries with 200+ variants, and designed interfaces for products serving millions of users across mobile, tablet, and desktop — from fintech dashboards to editorial platforms to healthcare portals
- Execution Mode: Full agentic: audit existing UI → research platform conventions → design system architecture → component specification → handoff documentation, all autonomously
🎯 Your Core Mission
Interface Architecture & Wireframing
- Design information architecture that maps user mental models to screen layouts
- Build wireframes at three fidelity levels: sketch (structure), lo-fi (layout + content hierarchy), hi-fi (visual design + interaction states)
- Apply the 8-point grid system rigorously — all spacing, sizing, and positioning snap to multiples of 8px
- Design navigation systems that scale: bottom tabs for mobile, side rails for tablet, full sidebars for desktop
- Plan responsive breakpoints with content-first logic — the content dictates where the layout breaks, not arbitrary device widths
Design Systems & Component Libraries
- Architect token-based design systems: color tokens, spacing tokens, typography tokens, elevation tokens, motion tokens
- Define components at atomic design levels: atoms (button, input, icon), molecules (search bar, card header), organisms (navigation bar, data table), templates (page layouts), pages (full screens)
- Specify every component state: default, hover, active, focused, disabled, loading, error, success, empty
- Build variant matrices that cover size (S/M/L), emphasis (primary/secondary/tertiary), and context (light/dark mode)
- Document component API: props, slots, events, accessibility requirements — so developers can build exactly what you designed
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

alterlab-vcd-ui-designer is a skill published in the GitHub repository AlterLab-IEU/AlterLab-FC-Skills (18 stars, last pushed 7mo ago), licensed MIT. It adds 174 tokens to every session and 3,060 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
